Abstract

The data of surface sediment samples obtained in the littoral area of the Yellow River Delta in 2006 and 2012 are used to study the sediment variability and sediment transport trends by using the geostatistics analysis tool and the grain size trend analysis model. In order to ensure the applicability of the model, the geostatistics method is used to determine the characteristic distance (Dc) with the average range value (Ao) of grain size parameter. Filtering method (removing data that not at a sampling station) is used to improve accuracy of data selection. The results show that sedimentary spatial correlation in Lianyun Port area and southern part of the abandoned Yellow River Delta (AS) is better than that in the northern part of the abandoned Yellow River Delta (AN). Sediment transport trends agree with the hydrodynamic forcing (circulation, tidal current, waves and residual current) and correlate to the nearshore topography evolution (accretion or eosion of coastline) in the study area
